The' essential object of this invention isto providea machine for sharpening razors, and the machine is adapted both to hold a razor or razor j revolving honing stone and .a stropping roller and to move the razor or blade lengthwise of the roller or rollers.

In the drawings, Figure 1 is an end elevar- Vtion of the machine; Fig. Qfis a side elevation of the machine; Fig. j view of the are to be sharpened;

are views at right angles 'The main 'shaft 1v extends from end to end of the machine, being supported in any suitable manner by the framework whichl comprises uprights or legs 2. and 'the crosspieces 3. At one end of shaft 1 is pulley 4 which can rotate idly upon the shaft, but whenthe clutch 5 is forced. toward the left, Fig. 5, and into the conical recess 6 of the pulley as to rotate in unison, it being understood that the clutch-head 5 is splined upon shaft 1 at 7.

'l y of shaft 1 is communicated to the pulley 10. lhe small crank-arm 13, Figs. 2 and 10, is eccentrically Aconnected at one endto pulley 1Q by pin 14,and at the other end ksaid arm 13 is .perforated andtlirough this` per# foration pin 15 passes'. Said pin -is retained by the ears of brackets 1G which project outwardly .from lthe cross-head 17 ,which member 17 in turn is secured to the rods 18. It will be obvious, therefore, that by the devices, *best shown in Fig. 10, a continuous rotation of shaft 1 and pulley 10 -is adapted to be translated into longitudinal reciprocatory movement 4of i is supported upon. the vslidable Aframe 17, 1S, and'said blade-holder 19 is formedof 1a metal plate 2.0, 21 bent as best shown in section Iin Fig. 4. The lower half '2O of the plate may be perfectlyflat, while the upper half or section 51 is bent so that one 'edge is adapted to come into close contact with the lower section 20, whereas, at its middle theA portion 21 is spaced apart 'from the lower portion Q0.- The portions 2O and 21, therefore, pair of jawss.

er portion 21 The blade-.h0lder`19' (-see Figs. 3 and 4) .Asshown in Fig. 3, theupis slotted so as to divide the into four separate units, though this number maybe upperand lower sections QO'and 21, and the knob or nut Q3 is adapted to screw upon the threaded end of member 22. The blade or blades 24, which are to be sharpened, are clampedbetween the edges ofinembersQO and 21 and are held in place by tightening the nut 23. Theshaft 25 v,is

the members 20 and 21 and said shaftA 25 projects outwardly beyond the ends'- of the blade-holder. l,

The guide 26, which is merely a U-*shaped piece of metal, is adapted to swin upon the member Q5 as a shaft from the l line potion the guide tion for the extreme outer edge of the blades 24 which are to'be sharpened, and 4after the blades have been properly adjusted .in place andl .clampedbetween the redges t th dotted line position` so as to beout of the act 'as ay spring-like clamp orA l varied at will." A screw or bolt 22 passes through both the'l sition, Figs. 3 and 4, to the dotted line po. sition in said iigures.

way and out of engagement with the rollers Rigidly fixed to the holder 19 is 2 9 made of spring-metal or the and by this shank, as will hereinafter the shank like,

appear, -the holderitself is caused. to rock 28, it follows that the movement of the 4ol they will be `vuided The'outer left to right, Fig. 2,

shank 29 will cause .the edges, which arev to be sharpened,- lirstto engage the roller 27 and then to engage the roller 28 and since .the shank 29 is' made of spring metal it will be Asi'ifficien'tly resilient to yield when the blade com esinto -contact with either of the rollers, and in this manner the blade will be held tightly enoughagainst the rollers to secure the necessary abrading effect but not so tightly'as to cause the machine to bind.

Secured'to. the floorand projecting upwardly through the space between the rods -18 are standards 30, and at the upper end of each of said standards is Va suitable fork 3'1, the height of which can be .adjusted by the lthumb-screw 32. `Each of said .forks 31 holds a. slotted plate Orcam 33, and through the slots 34 o f said plates the outer ends of the slianks 29 are adapted' to project. The standards v30 are fixed vin position, but the Shanks 29 will be carried from.

and from'. right'to left beca-use of the longitudinal reciprocation of the framework 17, 18,'upon which the bladeholders 19 are carried; and as the -Shanks .29 are pushed first in one. direction or the other,

by the slotted plates 33. enads of shanks 29,2. e.. the. ends farthest removed'froin the rollers 27 and 28, 'will be raised as the sliding framework moves in one direction, and will be lowered as'it moves in the opposite direction, and conversely those edges 'of fthe blades 24 which are to be sharpened Willbe lowered and brought into engagement with the roller 27 as' the sliding framework moves. in one direction, and will be lifted, and-'broughtv into Contact with the roller 28 when the sliding framework nieves in the opposite direc-V tion. l

The roller 27 is supported upon a shaft 35 at one end ofwhich isa pulley 3 6,- aiid the roller 28 is supported upon a shaft 37 which carries a pulley 38. The shaft .1 carries a pair of pulleys 39 and from pulleys 39 belts 40 extend to .pulleys 36 and 38, one of the belts being crossed so as to drive the rollers 27- and 28 in opposite directions. .The roller-27. may conveniently7 be made of lioning stone, and tlieroller 28 maybe covered ,iwith leather, canvas, or other stroppinginir sharpened .will just reach the rollei's'27 and and which nut 45 to ride slowly terial, or the rollers maybe constructed in any other manner so as to enable them to pei-forni the function of blades 24, which arebrought into'contactvfirst with one roller and then with the other.

sharpening the f upon said threaded end44, the two halves of said nut being normally held together and pressed -into engagement with the screw threads 44 by the helical springs 46, which springs -46 encircle rods 47, which are se-` cured to-the upper half `ofthe split nut 45 project through suitable perforations in the lower halfoff said nut. Said rods 47 have' caps 48 at their lower ends and the springs 46 are between the caps 48 and the under surface of the lower half of the split nut 45 so that said `lower half is constantly pressed. upwardly. Y

The lever 49` 's pivoted at 50 to the blocks 51 which are bolted to the floor, and said lever 49 is bent at 52. Bolts or pins 53, which are rigidly secured upon each side of the lever49, have their inner ends projecting .into the groove-54 upon the clutch head 5.

The split n ut 45 is pivoted at 55 Yto the' arin 56, which arm is '.slotted at 57 and is provided with a handle58. Through the slot 57 the pin 59 projects and said pin 59 eX- tends from oneI side to the'other of Athe yoke .G0 which is at the upper end of the lever 49.

The rotation ofthe shaft'41 causes the split toward the right, Figs. 2 and 5, and' when the arm 56 has been forced sufliciently far toward the right so that' the left-hand endof the slot 57 bears against the pin 59,l theupper end of the lever 49 will likewisebe carried towai-dtlie right; and as the lever 49 thus moves, the conical head 5 will be carried out of the recessG, thus releasing the., shaft 1 from the pulley 4 and stopping the operation of parts which are driven by the shaft 1.. In this manner the length of time' during which the sharpening process is permitted, to continue canbc vregulated at will, for the sharpening .'.p'rocess stops whenever the split nut 45 has movedso `far .toward the right, Figs. 2 and 5, as to cause the release of the clutch, and thc time during which the process continues depends upon. the distance which the split iiut 45 moves from left'to right. The pulley 4 'may be continuously driven by a belt which is actuated by a line shaft, not shown.

llie blades to'be sharpened are placed iii position while the. shaft 'i' and the moving parts driven thereby are at rest, i'. ci. while vthe clutch headv 5 is unlocked from pulley -l-.

When it is desired to commence sharpening a blade vor blades, the operator gi'asps the 68 which bear upon the rods 25 and serve to the tension being main' left, Figs.

handle 58 and pushes the arm. 56 toward the 2 and 5. When the operator pushes the handle 58 toward the lett, Figs. 2 vand 5, the split nut 45 will ride over the beveled threads #le which act as a ratchet. When the nut is allowed to grasp the threads 4.1L, the rotation of the shaitel will torce the handle toward` the right, saine being manually moved from right to left as desired, but when the parts are moved to the eXtremelett-hand position, the clutch 5 will lock the shaft l to the pulley (l, thus causing the machine to -be driven. As the' sliding Jframework 17, 1S is thus carried back and forth, the blades 24 have their edges tiret presented to the revolving roller 27 and then.

to the revolving 'roller 28, and while the edges are being so presented-to the revolv ing roller, the holder 19 isinoved lengthwise with respect to the rollers?? and Q8, and the bladesQl are, therefore, moved lengthwise of the roller at the same time that their edges are being .abraded by the roller. a. true stroppingmotion is communicated vto the blades.

ln order to support the blade holder i9 upon the sliding framework 1'?, 18, uprights 6l are provided. lnltig. 2 such npr are shown. The end uprig-.hts ill.. are

vided with lag screws 62 which project.

'through' said member 6l. each screw e?. bearing against an end 'of the redor shaft Q5. To the middle upright 61 and on each side thereof are bolted the pillows di within Whicl the opposite ends of the shafts are received. The plate S5 is secured by screws 66 to said middle upright 61, and. tl?, which have small ltnobs ZO vsecured to their upper ends, project .through said plate At their lower ends said rods 67 carry blocks hold them in place, tained by the' helical springs 69,' which encircle the rods '67 between the blocks 68 and plate 65. .ll/Then thebladeholders 19 vare being. assembled one-end; ct the shaft Q5 is placed between the pillovr 64: and the block 68,' the' block 68 being lifted upwardly as .the knob is pulled to the dotted'line position,

ll'igz; and against the other end the lag screw 62 is tightened, and in this manner each of the two holders 19 shown in the drawings is piv'oted between the middle np right 61 and 'one of the end uprights.

ln the drawings, particularly Figs. 2. and 3, the blade-holder 19 is depicted as being made in-our sections, each ot Which can. be tightened independently ot the others, and each holder 19, therefore. is adapted to hold and retain tour blades of the size andL shape ordinarily used in but it is obvious thatfthe machine is not re stricted to use in sharpening satety razor blades but may, by slight obvious inodica- L: M tu., @1mm nl the holder 19. he used. to
